It has -lain in wait 13 years before being found! The bug was introduced -in zlib 1.2.2.2, with the addition of the Z_FIXED option. That -option forces the use of fixed Huffman codes. For rare inputs with -a large number of distant matches, the pending buffer into which -the compressed data is written can overwrite the distance symbol -table which it overlays. That results in corrupted output due to -invalid distances, and can result in out-of-bound accesses, -crashing the application. - -The fix here combines the distance buffer and literal/length -buffers into a single symbol buffer. Now three bytes of pending -buffer space are opened up for each literal or length/distance -pair consumed, instead of the previous two bytes. This assures -that the pending buffer cannot overwrite the symbol table, since -the maximum fixed code compressed length/distance is 31 bits, and -since there are four bytes of pending space for every three bytes -of symbol space. ---- - deflate.c | 74 ++++++++++++++++++++++++++++++++++++++++--------------- - deflate.h | 25 +++++++++---------- - trees.c | 50 +++++++++++-------------------------- - 3 files changed, 79 insertions(+), 70 deletions(-) - -diff --git a/deflate.c b/deflate.c -index 425babc00..19cba873a 100644 ---- a/deflate.c -+++ b/deflate.c -@@ -255,11 +255,6 @@ int ZEXPORT deflateInit2_(strm, level, method, windowBits, memLevel, strategy, - int wrap = 1; - static const char my_version[] = ZLIB_VERSION; - -- ushf *overlay; -- /* We overlay pending_buf and d_buf+l_buf.

As each symbol is consumed, the pointer to the next -+ * sym_buf value to read moves forward three bytes. From that symbol, up to -+ * 31 bits are written to pending_buf.
